Hi everyone

I have some problem to order an array by a field of this, here i leave the example

foreach($xml as $site){
echo '<div><a href="'.$site->loc.'">'.$site->loc.'</a>' .$site->padre.'</div>';
}

Some times the filed $site->padre is empty but i'd like to order by $site->padre alphabetical i saw example with usort but i don't understand how to work it.

Thanks in advance.

Cheers
